How to make M&M Sheet Cake Cookies with a Cake Mix
Combine the cake mix, eggs and oil in a medium bowl. Mix together using a hand held mixer {or by hand}.
Once you have a thick dough, add the mini M&M’s and mix with a spoon to evenly incorporate them into the dough.
Using a medium cookie scoop, scoop mounds of dough onto a silicone {or parchment} lined baking sheet.
Bake in a 350 degree oven for 9-11 minutes. Remove from the oven and allow the cookies to cool on the baking sheet for at least 5 minutes.
Sheet Cake Cookie Frosting
To make the frosting, add the butter, milk and cocoa to a medium sized saucepan.
Cook over medium heat until the butter is melted. Remove from the heat and add the powdered sugar.
Whisk until you have a smooth and silky frosting.
Take the frosting and spoon a heaping teaspoon full onto each of the cookies.
Spread it out with the back of a spoon and then sprinkle with a few remaining M&M’s.
Allow the frosting to set up before stacking the cookies on top of each other. This takes about 30 minutes.
If you can’t wait that long then eat one {or three} while you wait.
CAKE MIX COOKIE BAKING TIPS
- Use a whisk to break up any lumps in the cake mix before adding the other ingredients.
- Whisk the two eggs together before adding them to the cake mix. This is especially important when you are mixing by hand.
- Always use a cookie scoop when making cookies because when they are all the same size they bake evenly {see my other cake mix cookie baking tips here}.
- Do not over bake. It is so important to remove the cookies before they are totally set. The difference between a perfectly baked cookie and an over baked cookie is only a minute or two.
- Allow the cookies to cool on the baking sheet for at least 5 minutes. The heat from the baking sheet will allow the cookies to continue baking slightly and set up just right.

Cookies
- Preheat oven to 350 degrees.

- Add mini M&M's to the dough and stir in with spoon until they are evenly incorporated.
- Using a medium sized cookie scoop {or heaping tablespoon}, scoop cookies onto a silicone {or parchment} lined cookie sheet.
- Bake for 9-11 minutes, remove from oven and let cool on cookie sheet for at least 5 minutes before moving them to a cooling rack. Repeat until all of the dough is baked.
Frosting
- Combine the butter, cocoa and milk in a medium saucepan over medium heat and whisk until the butter has melted. Remove from the heat, add powdered sugar and whisk until smooth.
- Spoon a heaping teaspoon of frosting over each of the cookies. Use the back of the spoon to spread the frosting out. Sprinkle the top of each cookie with a few additional mini M&M candies before frosting has set up. NOTE: Working on one or two cookies at a time works best.
- Let frosting set and serve. Keep your sheet cake cookies in an air tight container at room temperature for up to 3 days.
